DSG 6 DQ250 TCU repair
24-month warranty2–5 day turnaroundTracked return deliveryNo coding needed
We repair the DSG 6 DQ250 TCU, fitted to Audi, Seat and Skoda models. Listed under part numbers 02E927770AR and 02E325025AR. Send us your original unit: we test it on the bench, replace the failed components on the circuit board, then test it again before it goes back to you — usually within 2–5 working days. You get your own unit back rather than a replacement, so it keeps the coding and security data already matched to your car — no programming or dealer visit needed. Every repair carries a 24-month warranty.
Not sure the TCU is the cause? The symptoms and the fault codes we see on this unit are listed under Common Faults. If your codes differ, send them over before ordering — if the unit turns out not to be faulty you only pay the test fee and return postage.
Which vehicles does this TCU fit?
This unit is used across Audi, Seat, Skoda and Volkswagen. Check your exact model and year under Matching Vehicles, or compare the number printed on your own unit with the part numbers listed on this page. The same hardware often appears under several part numbers — call 01884 798090 if yours is not shown.
Prefer not to remove the unit yourself?
Choose the on-site option and bring the vehicle to our workshop in Uffculme, Devon. We remove, refit and road-test it before you drive away, usually the same day.

Frequently asked questions
Does the unit need coding or programming afterwards?
No. This is a repair, not an exchange — you get your original unit back, so it keeps the coding and security data already matched to your car. Refit it and clear any stored fault codes with a diagnostic tool.
How long will I be without the unit?
We aim to complete all repairs within 2–5 working days. Should a repair take longer, we will contact you with an update. It goes back to you on a tracked service. Ask about on-site fitting if you need the car back the same day.
My part number isn’t in the list — can you still help?
Usually yes. The same hardware appears under many part numbers. Send us a photo of the label or call 01884 798090 and we’ll confirm before you send anything.
What warranty do I get?
Repairs of this unit carry a 24-month warranty. See Returns & Warranty for the full terms.
Will the warning light go out after the work?
Yes, once the unit is refitted and the stored codes are cleared, provided the fault was in this unit. If a related wiring or sensor fault is also present it has to be fixed separately — we tell you what we found.
